Although no evidence of foul play was immediately found, Kondratjeva`s death was being investigated as a possible homicide, Deputy Pete Fosselman said.

Fosselman said the roof of Kondratjeva`s car was crushed when it fell 25 feet from the highway and landed at the water`s edge. The woman`s body was protruding from a back window.

``Homicide detectives are looking into the case due to the body`s unusual position in the car,`` Fosselman said.

Detectives were unsure how the body got into the back seat of the car, Lt. Chuck Bradley said. An autopsy was planned.

Kondratjeva, who was an athlete in the Soviet Union before coming to the United States, had testified at the espionage trial of Miller, the first FBI agent ever charged with spying.

In her testimony, Kondratjeva said convicted spy Svetlana Ogorodnikova had invited Miller to a dinner party at her home, and that Miller told her he was a lawyer. Prosecutors charged that Miller lied about his profession as part of his alleged spying activities.
